Using inverter-driven technology with Mitsubishi Electric BLDC compressors and offering capacities of up to 140kW for down flow and 105kW for up flow configurations, the manufacturer says the range is well equipped to deal with a variety of data centre and computer room applications.

Air conditioning manufacturer Aermec has launched a new water-cooled chiller offering energy efficiency even at partial loads.

The WMG is described as a compact chiller designed for indoor installation. It has high efficiency two-stage magnetic levitation centrifugal compressors, which allow the refrigerant circuit to be oil free. It also has a very low starting current and uses 50% less refrigerant thanks to its patented spray technology within the heat exchanger. In addition, the WMG delivers savings on installation and maintenance.

Carrier has launched its new AquaForce Vision 30KAV chillers in the UK and says the range sets a new benchmark for efficiency.

The first phase of the new 30KAV range of variable-speed screw chillers, equipped with Greenspeed intelligence, covers cooling capacities from 500 kW up to 1100 kW, and claims exceptional levels of seasonal efficiency. It will be followed later this year by the introduction of the AquaForce Vision PUREtec 30KAV-ZE, designed exclusively for the low GWP refrigerant HFO R1234ze.

BITZER has introduced its new ORBIT+ scroll compressor series at Mostra Convegno in Milan.

The new models allow system manufacturers to fulfil the requirements of the European Ecodesign Directive. They feature a line start permanent magnet motor, which achieves efficiency levels that improve the seasonal performance (SEER/IPLV) by up to 8% while also increasing cooling capacity by up to 5%.

The AquaForce Vision 30KAV with Greenspeed intelligence, with a first phase covering cooling capacities from 500 kW up to 1100 kW, is equipped with variable-speed screw compressors and variable-speed fans – AC as standard and EC as an option – as well as optional variable-speed pumps.

​It automatically adjusts the cooling capacity and water flow to match the needs of the building or process load variations. The result is optimal operation at both full load and part load. This new range of chillers has a SEER of up to 5.5 in cooling mode, and an Energy Efficiency Ratio (EER) of up to 3.49 at full load. 30KAV offers energy efficiency up to 40% higher than the 30GX range with the same footprint.

CIAT Group and subsidiary Cristopia Energy Systems has launched a thermal energy storage system in the UK and says it helps to reduce the load on chiller and electrical power requirements by between 30 and 70 per cent for cooling production.

The CIAT Cristopia system is designed to reduce end users’ energy costs by shifting away from reliance on peak day-time power by harnessing off-peak electricity at night. It reduces the load on the chiller by smoothing-out peaks in the daily load profile, in the process also reducing chiller maintenance costs and the size of the combined refrigerant charge on a site.
